APPARATUS FOR WEAVING FIGURED FABRICS.

SPECIFICATION forming part Of Letters Patent N0. 621,776, dated March21, 1899. lApplication filed December 20, 1898. Serial No. 699,862. (Nomodel.)

T0 all whom, t may concern: l

Be it known that I, ROBERT Husein, Jr., a subject of the Queen ofGreatBritain and Ireland, residing at Kirkcaldy Power Loom I-.inenWorks, Kirkcaldy, in the county -of Fife, Scotland, have invented a newand useful Improvement in and Relating to Apparatus for Weaving FiguredFabrics, of which the following is a specification.

My invention relates to improvements in the weaving of gured textilegoods, the object being to apply to looms apparatus which will allow ofa design being woven on the cloth independent of or in addition to astandard design which is produced by the ordinary cards and to makeprovision for the changing 0 such designs at the discretion of the operaor.

It is sometimes desirable that certain pieces of cloth, such as hoteltowels and the like, be woven with the name of the hotel or theproprietor thereon in additiony to the ordinary pattern. When thequantity of cloth ordered is small, the expense incurred in preparingcards with the required name, gure, or design is quite out of proportionto the cost of the goods as made without such specialsupplementaryname,gure,ordesign. By means of my new and improvedapparatus any suitable required design m'ay be added to or substitutedfor the standard design at a small additional cost. I attain theseobjects by the mechanism illustrated in the accompanying drawings, inwhich- Figure l is a side elevation of those parts of the loom which arenecessary to show how the jacquard uprights may be actuated by thesupplementary or subsidiary pattern. Fig. 2 is a plan showing how theneedles may be constructed in order that they may be suitable foractuation by the subsidiary pattern. Fig. 3 is a view similar to Fig. l,but showing the feelers clear of the subsidiary pattern and the uprightsvertical. Fig. 4. is a side 4elevation ofthe necessary cams. Fig. 5 is apart front elevation showing how the subsidiary pattern-cylinder may beactuated. Fig. 6 is an end elevation of same. Fig. 7 is a frontelevation showin a modified form of subsidiary pattern-cy inder, andFig. 8 is an end elevation of same.

Similar letters and numerals refer to similar parts throughout theseveral views.

I weave the gured cloth by means of a main pattern-cylinder A and cardslO in the usual way, producing thereby the standard design. When it iswanted to introduce the supplementary or subsidiary design,the cards maybe disengaged or rendered inactive by punching where wanted and thesupplementary or lsubsidiary design woven in the cloth by means of aspecial pattern 1l, which through suitable connections controls theuprights of the jacquard, such special pattern taking the place of theordinary cards. A complete design can be woven by means of such specialpattern and its appurtenances and that without the aid'of the'ordinary-cards. The pattern-cylinder 12 vis of suitable diameter andwidth, and I give to it a suitable rotary or rotary and transversemotion. On such cylinder I fix the required pattern 11, such patternbeing preferably cut yout of sheet metal and so placed relatively to thesurface of the cylinder that there is aspace beneath to allow of thepoints of the supplementary feelers or needles (which are afterwarddescribed) passing into it. It is to be understood that although I havesaid a sheetrnetal pattern may be used, yet any other method by which anindented or perforated surface of definite design may be applied to thecylinder will serve equally well. of a cylinder I may use a iiatplate'for carrying the pattern, giving to it the desired niotion bysuitable mechanism.

The drawings illustrate how the subsidiary design ll may be made toactuate the uprights, and only the necessary parts of the loom requiredto illustrate this are shown.

The pattern-cylinder l2 may be made to intermittently move around atintervalsof one, two, or more shots.

of a lever 13, which is lifted by a cord actuated Aby a suitableuptake-cam 27. 14 is a pawl which engages with and inter- Instead Thisis done by means mittently pulls around a ratchet-wheel 15, which inturn causes the wheels 16 and 17 to rotate, the latter moving around theworm 18 and worm-wheel 19, which is keyed to rotate with the shaft ofthe cylinder l2.

The feelers 2O are of met-al, and their lower points are arranged inline to pass, side by side, through a slot in the guide 21, such slotbeing provided with partitions to keep the feelers in position. Theneedles are connected to the feelers by the cords a b'.

In Fig. 1 I have shown one needle, 0;, with its feeler 2O resting on thetop of the pattern f and the other, b, with its feeler 20 off suchpattern-that is to say, the needle a, isnot influenced by its feeler,because its weight is supported by the pattern, and therefore theuprights 22 are not clear of the brander 23, and consequently they willbe lifted when such brander rises and the warp will be raised just as ifthe needle had passed into the hole in the card. The needle b, on theother hand, is influenced by the pattern 11 because the feeler 2O isunsupported by such pattern, and consequently its weight pulls theneedle b forward, this action being assisted by the forward motion ofthe guide 28 at the moment of releasing the hooks, and so causes theuprights 24 to clear the brander, which will rise without lifting themand the warp will not be raised, even though such needle b be opposite ahole in the card.

Fig. 3 shows all the feelers 2O lifted clear of the pattern Il. Thisoperation is performed by lifting the brander 25 by means of the lever26such lever being actuated by a suitable cam 35, the feelers beinglifted clear of the pattern previous to the moving of the cylinder. f

The guide 2S is shown in its upward position in Fig. 3. Its movementtakes place at every shot by means of the double cam 29 and the lever30. In the drawings I have shown the three cams 35, 27, and 29 mountedon the same shaft, such shaft being arranged to rotate in the directionof the arrow once for every two shots. The cam 29 tightens the cord andactuates the lever 30 at the moment of selection of the uprights by thebrander 23, thus moving the guide 28 into the position shown in Fig. 3.Immediately after the selecting-cam 29 is cleared the feeler-frame cam35 begins to act, and when such frame 35 is fully lifted the uptake-cam27 commences to operate and to move forward the pattern 11. It isobvious that the cams 35 and 27 should work synchronously, although theyneed only be timed to act as often as is considered necessary for thekind of cloth being woven, but the selecting-cam 29 must operate atevery shot.

One of the uses to which my invention may be put is as follows: It issometimes desirable that a name or particular device be woven on cloth,such device being in conjunction with any other desired pattern. Ifcards only be employed to produce such a combination, they must bespecially cut. By employing the supplementary pattern the ordinary cardsmay be used to produce the standard design and the supplementary designmay be added at intervals, or it may be interwoven with the standarddesign, as may be found desirable.

Instead of merely causing the pattern-cylinder 12 to rotate, aspreviously described, I may cause it not only to rotate, but also tomove laterally along its axis and so cause a spiral pattern to comebeneath a group of feelers, in this manner weaving a long and narrowdesign. One way of carrying this into eect is illustrated by Figs. 7 and8. The worm-wheel 19 is splined to the shaft of the cylinder 12 by meansof a sliding key in order that such cylinder while constrained to turnmay be free to move laterally. A spiral guide 31, witha slot or groove32 in it, is fixed to the cylinder 12. A wheel 33, which is free torotate, but which cannot move laterally, is carried by a bracket 34,fixed to the guide 21. The rotation of the cylinder 12 causes the spiral32 to bear against the iiXed wheel 33 and so constrains such cylinder tomove sidewise.

Although I have illustrated and described how my invention may beapplied to a Jac= quard loom, yet it is evident that the arL rangementand construction may be modified without departing in any way from thespirit and scope of my invention. Y

Having now described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. In combination, the needles a, b, the main pattern-cylinder foroperating them, the' uprights controlled by the needles, means forraising the uprights, a supplemental patterncylinder and connectionstherefrom to the needles a, b, whereby said needles will be acted onboth by the main and supplemental pattern-cylinder, substantially asdescribed.

2. In combination, the main pattern-cylinder, the needles controlledthereby, the up; rights controlled by the needles, the brander foroperating the uprights vertically, a supplemental pattern-cylinder,feelers actuated by the supplemental pattern-cylinder and conectionsbetween said feelers and the needles, substantially as described.

3. In combination, the needles, the main pattern-cylinder for operatingthem, the uprights controlled by the needles, means for raisin g theuprights,a pattern-cylinder, means for rotating it, means for giving itlongitudinal movement comprising the spiral guide and the feelersbetween said cylinder and the needles, substantially as described.

4. In combination, the needles, the main pattern-cylinder for operatingthem the up- IIS and means ,for operating the brander 25, sub- Iostantially as described.

In witness whereof I have hereunto set my hand in presence of twowitnesses.
